I tried to suicide ingame and the following happened: -Unavailable URL- (this had me stuck over the Outpost Campfire and i tried to click once like hit in the air, it crashed. tried to move, cam was buggy as f***) Second time I tried to suicide, i stuck again over the Outpost Campfire and tried to hit again in the air, afterwards it shutdown the server and it told me: “Connection Lost - Attempting to attack an invalid entity” Please tell me if you need more informations

Likely closable in the port.

*vanilla as in just aether

Gonna go ahead and confirm this, as it's happened to me before as well several times in an entirely vanilla aether environment.

The problem doesn't seem to happen in vanilla and with all your mods I'm just going to mark this as mod incompatibility for now.
